sick goldfish ?

Question
hi samantha,

i have a 60 gallon tank with 3 goldfish,
1 koi, and 1 snail. the snail and the smallest
goldfish i've only had for about 6 weeks. but the
others i've had for 4+ years and one of them suddenly has started acting strange. he sits at the bottom most of the time, sometimes slightly
tilting to one side a bit. he still becomes active at feeding time but seems to spit out as
much food as he takes in. is he sick, or just old? is my tank ok?

     thanks, bobby


Answer
Hi Bobby,
I don't think he's sick I think he is just getting old. 4+ years is ver impressive. You must be a wonderful pet owner. I'll still give you a website just incase he is sick so you can diagnose him. http://www.goldfishinfo.com/diagram.htm
Hope I helped and hope hes alright,
